Application Description

Edgebanding with hot melt adhesives

For decades, edgebanding of wood-based panels with a variety of edgebands has been an established practice in the furniture industry. The quality demands concerning visual appeal, the technological progress in engineering, and also the almost unlimited diversity of materials to be processed - all of these factors represent special challenges for the adhesive technology. In modern, high-quality furniture manufacture, the quality of the edgebanding is increasingly becoming a key criterion for evaluating the quality of the entire furniture item. The end customer demands a glueline that is hardly visible and perfect.

Modern, thermoplastic and moisture-curing reactive adhesives ensure superior bonding strength and high-quality appearance in edgebanding applications. A broad spectrum of adhesion to different edgeband materials is equally important as fast adhesive setting for direct downline processing and high heat resistance and durability. PUR hot melt adhesives are renowned for meeting the highest demands with regard to a zero-bondline appearance as well as resistance to heat, moisture and chemicals in kitchens and bathrooms. Jowat supplies these hot melt adhesives of the latest generation also in granulate form. The ease of processing makes them particularly attractive for processers who have not used the PUR technology before. Therefore, Jowat hot melts provide the ideal process solution for every edgebanding application.

Application Tips

Directions for use

PUR hot melt adhesives can be processed on throughfeed lines at different feed speeds, as well as on roller and nozzle applicators. All parts of the melting and application units coming into contact with the adhesive should have a non-stick coating to prevent possible catalytic reactions due to metal contact. A non-stick coating will also facilitate a considerably easier cleaning.The melting and application units should be equipped with a precise temperature control to prevent local overheating and unwanted secondary reactions. Heating the adhesive to a temperature above the recommended processing temperature will usually lead to a fast increase in viscosity of the melt due to a so-called thermal crosslinking reaction in the adhesive (the allophanate reaction), which is triggered by heat and does not need moisture.

Cleaning

If necessary, flush out hot melt remnants from the melt and applicator units with flushing agent Jowat® 930.94 (red). Crosslinked, solid material has to be dissolved with cleaner Jowat® 930.60 (please test for suitability before use).
